World Meteorological Organization (WMO)
191 Member States and Territories
Mission (summarised):
To facilitate worldwide cooperation in meteorology, hydrology
and related fields by:
• establishing networks of observing stations
• maintaining centres providing meteorological and related
services
• establishing systems for data exchange
• defining standards for observational data and its publication
• application of meteorology to aviation, water issues,
agriculture, shipping and other human activities
• promotion of operational hydrology and cooperation
• encouraging research, training and coordination
Commission for Hydrology (CHy)
Mission:
To design and execute the water related activities of WMO,
including promoting the exchange of technology and
capacity building. In particular, CHy provides guidance
to WMO Member countries and the WMO Secretariat for
the implementation of the Hydrology and Water Resources
Program of WMO.

Data Operations and Management
• Guide the implementation of CHy-14 Resolution 7/1 that began “a
process, including testing, that could see the potential adoption of
the WaterML 2.0 as a WMO standard for information exchange
managed by WMO (supported by the WMO/OGC MOU) and to
register this standard as a joint WMO/ISO standard”;
• Monitor and report on new developments dealing with data
management issues, such as observations, data exchange and
protocols, data transfer formats, and WIS and WIGOS;
• Review progress with respect to the exchange of hydrological data
and products, and propose additional guidance on data that should
be exchanged, including harmonization of exchange practices.
INTERNATIONAL RESOLUTIONS
WMO Res. 40 (Cg-XII) - WMO policy and practice for the exchange of meteorological and
related data and products.
Members shall provide on a free and unrestricted basis essential data and products which
are necessary for the provision of services in support of the protection of life and property
and the well being of all the nations…
WMO Res 25 (Cg-XIII) - Exchange of hydrological data and products.
Members shall provide on a free and unrestricted basis those hydrological data and
products which are necessary for the provision of services in support of the protection of
life and property and the well being of all the nations…
WMO Congress of 2012 noted the considerable work being undertaken internationally with
respect to the development and agreement on standards for the transfer of hydrologic data
between data servers (databases) and users.
WaterML 2.0 was proposed for adoption as a WMO standard for information exchange.

WIS
WMO Information System
WIS distinguishes centres as Global
Information System Centres (GISCs), Data
Collection or Production Centres (DCPCs)
and National Centres (NCs). NCs and
DCPCs collect, generate, or distribute
data, forecasts, and other processed
information. NCs are national in scope.
DCPCs are international in scope and
each is associated with a particular WMO
Programme. GISCs support all WMO and
co-sponsored Programmes, maintain the
comprehensive metadata catalogue, and
help to ensure the accessibility of WMO
data and information globally.

GEOSS and WIS
WIS is an exemplar
contributing component of the
GEOSS for weather, water,
climate and disaster. WMO
users can discover
information in GEOSS via
their GISC. Similarly, GEOSS
can discover information in
WIS via the GISC catalogues
through the GEOSS common
infrastructure
HYCOS
HYdrological Cycle Observing System
• Project Initiation Stages
– Stage A: Request stage
– Stage B: Concept stage
– Stage C: Project proposal stage
• Project Implementation Stages
– Stage D: Preparatory implementation stage
– Stage E: Field implementation stage
• Post Project Stage
– Stage F: Project maintenance stage
ICG-WIGOS – Task Team on
WIGOS Metadata (TT-WMD)
• Terms of reference:
•
To identify the information that is needed to allow the majority of users to use
WIGOS observations in appropriate contexts and in a defensible way.
•
To create the WIGOS Core Metadata Standard that allows the essential
information to be exchanged unambiguously, regardless of the format used for the
transfer…
• Principles:
•
Include the information that enables users to make adequate use of observational data [also for climate
applications]
•
Every piece of metadata shall have date/time information associated with it
•
All metadata associated with internationally exchanged data shall be made available
•
Metadata shall be updated in a timely manner to support adequate interpretation of data
•
Standard should be applicable to all disciplines forward-looking but also respect legacy (e.g., Vol. A)
•
Standard should be acceptable and applicable to all Members
Draft WIGOS metadata categories
Draft WIGOS Metadata Standard ‘model’
TimeSeriesML proposal
• 2012 – CHy recommends testing of WaterML2: Part 1 for data exchange and progress
towards adoption as a WMO/ISO standard
• 2013 – CBS IPET-MDRD is tasked with carriage of the standardisation process
• 2013-14 – IPET-MDRD recognised benefits of a generic time series model for weather,
climate, water… (observational) data
• March 2014 – IPET-MDRD proposes development of TimeSeriesML based on
WaterML2: Part 1
• June 2014 – Initial scoping work: BoM, CSIRO, Met Office. CHy consulted
• To be further discussed on Thursday
WaterML2 adoption

• Agreed web service endpoints (WMS, WFS, SOS) and configurations
• Documentation of commercial and non-commercial systems supporting
agreed implementation architecture on WMO web site
• Pilot implementations using a variety of systems in a variety of countries
• Training on water data sharing using standardized data formats and
service endpoints
• Support in the development of Central Web Service Registries for
National Hydrological Services shared globally through the WMO

WHOS
WMO Hydrological Observing System
In 2013 a WMO Hydrological Observing System (WHOS) was proposed by
the CHy Advisory Working Group as the means to provide the most
comprehensive hydrological component in fulfillment of the WIGOS
objective of “an integrated, comprehensive, and coordinated system which
is comprised of the present WMO global observing systems”.
WHOS is conceived as a portal to facilitate access to already available online real-time and historical data, drawing from the water information
systems of countries around the world that make their data freely and
openly available, including HYCOS projects.

World Hydrological Observing System (WHOS)
A couple of challenges for the HDWG
• Does HDWG have a framework for future standards development?
• What does our suite of water data standards look like in a few years time?
• WaterML2: Part 1, 2, 3, …N?
• How can HDWG influence take-up of developed standards?
• Can we assist with capacity building and implementation of standards-compliant
technologies for hydrological data sharing in countries around the world?
• For discussion during the workshop…
Conclusions





Water data sharing is essential for improved and more
transparent water resources management
The exchange of hydrological and related data needs to be
increased at national, regional and international levels
Tools and techniques need to be made available for the
optimization of hydrological data collection and related networks
of National Meteorological and Hydrological Services
Internationally agreed standards, formats and protocols will be
adopted by WMO to underpin the transfer of hydrological data
and information
Increased hydrological data availability will support more value
added products and services
